lo Another purpose. is the provision of improved wiring means andcontrol means for such a device.

Another purpose is the provision of an improved score indicating meansfor such a device.

20 Other purposes will appear from time to time in the course of thespecification and claim.

I illustrate my invention more or less diagrammatically in theaccompanying drawings wherein:

Figure 1 is a front elevation;

Figure 2 is a -section on an enlarged scale along the line 2 2 of Figure1;

Figure 3 is a front elevation of the target structure proper;

Figure 7 is a section on the line '|-'l of Figure 4; i Figure 8 is asection on the line 8--8 of Figure 3; 40 Figure 9 is a section on thelineS-B of Figure 3; and

Figures 10 and ll, taken together, constitute a wiring diagram.

Like parts are indicated by like symbols 4:, throughout thespecification and drawings.

Referring to the drawings, I indicates any suitable cabinet havingdownwardly extending supports 2 and a removable front panel 3. The saidfront panel hasan upper aperture 4 which may 50 be closed by a pane ofglass or equivalent member 5. A lower aperture 6 is closed by a pane ofglass 'I which is herein shown as having indicating numbers or signalsthereon from zero to ten, as shown in Figure 1, the purpose of which 55will later appear.

I illustrate any suitable cross pieces or supports 8 Within the cabinetI which may be provided with bearing sleeves 9 which in turn receivebearing pins II) mounted on any suitable panel 1|. I2 beingl means forholding the upper end of said panel whereby the panel is normally inupright position. The panel is provided with an aperture |3, the purposeof which will later appear. The panel II may be of metal and is hereinshown as provided With forwardly projecting bosses I4 to which the laterdescribed structure is mounted, and also forwardly projecting bearingsleeves l5.

Mounted in said bearing sleeves |5 are any suitable shafts IG whichreceive pulleys about which passes the belt I8 which may be of the V-belt type. I9 is a drive pulley on one of the said shafts which may bedriven by means of a belt from the motor drive pulley 2| associated withthe motor 22 herein shown as positioned in the aperture I3. Any suitablegear reduction structure may be interposed between the pulley 2| and themotor. vIt will be understood that when the motor 22 is energized thepulleys Il rotate and cause the belt I8 to move in the directionindicated by the arrow in Figure 3.

23, 24 indicate tracks which include horizontal parallel portions 25 andend portions 26 generally concentric with the axes of rotation of thepulleys Il. These tracks'may be mounted in any suitable fashion as byplates 2l which may be connected together by the cross pieces 28, theinner plates being secured to the bosses |4 as by any suitable screws29. Mounted for movement along the said tracks are carriages generallyindicated as 30, each such carriage having pairs of wheels or rollers 3|engaging the outer track surfaces and pairs of wheels or rollers 32engaging the inner track surfaces, the distance separating the axes ofthe outer rollers being slightly greater than that separating the inner,to permit the carriage to move readily around the arcuate portions ofthe track. I'he carriages 30 may include an upper platform 33, uponwhich is mounted a photo'electric cell 34 herein shown as provided witha forward chamber 35 which may be closed by the lens 36 the purpose ofwhich is to concentrate light upon the cell 34. The rest of the cell 34may be painted black or otherwise obscured or, if desired, may besurrounded by a housing, in order that the cell may be protected fromany light except that which passes through the lens 36.

Pivoted to the carriage 30 is any suitable target drop member 3l hereinindicated as in the form l Thus the carriage is toed by the belt throughthe of a duck and provided with an aperture 38 which, when the targetdrop portion is in upright position, is positioned forwardly of andalined with the lens 36. The target drop portion 31 may be pivoted as at39 andis herein shown as having a downwardly extending lever or levers40. It is normally held in upright position as by the springs 4I whichhave inwardly extending drop gripping portions 42, as shown for examplein v Figure 4.

` The carriage structure as a whole is moved along the tracks 23, 24 inresponse to the movement of the-belt I8 by a flexible connection whichincludes an eye 45. A link structure 46 is pivoted in the eye andincludes laterally extending terminal portions 41, 41, which engage sideportions of the carriage 30, in a pivotal relationship.

above described flexible connection.

49 indicates a removablescenery back drop and 50 a 'removable foregroundapron, the purpose being to simulate an outdoor scene through which thebirds or target drop portions may move with 'a f relatively vnaturalappearance. It will be clear from Figure li2 that the actuatingstructure for'` the targets is entirely concealed and only the targetdrop portions themselves are visible -to the user looking through theglass pane 5,

4It'will be understood that thepurpose of the invention is Vto vprovidea target' range which includes a moving target which can be shot at.with

a gun which shoots what may be described as bullets 'of light. Referringto Figure 11, I illustrate the gun generally indicated as 5i which isprovided with a lamp bulb or light source 52, the circuitl forwhich willlater be-de'scribed. It is also vprovided with a manually operabletrigger 53 which controls a trigger switch 54.' I'he device is initiallyput in play by inserting alcoin in the coin receiving'element 55 whichpermits it to be and the target drop portions'31, which move'continuously duringv the periodafter the closure of the coin switch 56,land continue to move until the operator has taken' his allowed shots. Inthe `present. structure, the Aoperatorv is permitted tenshots or tentriggerpulls and at the tenth trigger pull the device is put out ofoperation and the targets cease'to mover f (c) I n order to'limit thenumber of shots,-I `provide a shot limit yswitch mechanism which isreturned to initial position'when the coin switch i '56 is` closed andwhich is movedv one step at each trigger pull, the tenth trigger -pullserving Vto move theA shot limit switch to inoperative vposition withthe result that the operationV of the device ceases.

(di In 'order'fto indicate the score, I provide Iar generallysimilarswitch which is moved to zero position when thejcoin switch 56 isclosed. At the zero position, the zerolight of the window 1 isilluminated. At every hit recorded against one f of the photo'cell's34`,the nextY ensuing numeral. is illuminated. If the user gets a perfectscore, the number 10 is'illuminated at the last Shot and may remainilluminated to indicate the score until the device is prepared for anensuing user by the insertiony of a coin and the closure ofthe coinswitch 56. u

(e) In order to indicate a hit,l I also provide other indicating means.In the rst place, at each hit the target drop portion 31 falls forwardand, in the second place, a chime` sound's., A

(f) In vorder to make the device realistic', I also provide a thudsounder whichy may simulate a shot or hit, and which sounds at eachtrigger pull.

. Considering rst the shot limit switch mechanism,y I illustrate anysuitable base or plate 51 upon which is positioned any fixedarcuatecontactr58 whichr is' insulated and which is adapted to beopposed by therotating arm 59. When the device is in initialA position,the arm V59 is in the dotted une position in which it is shown in Figure11. Its movement is controlled by the ratchet 6l)r which is normallyurged in counterclockwise direction of rotation by thev spring 6 il butwhich is held against such rotation by fthedetent 62 urged into lockingposition by thefspring 63.

The reset magnet 64, when energized infresponr-:e to the closure of vthecoin switch 56, withdraws the detent 62 and permits the ratchet wheel 60and the arm 53 to be returned to the initial dotted i line position.Assuming that it is in the initial position, each -triggerpull, or eachclosure of the f e trigger switch 54 results in the energization of themagnet 6.5 -which in turn moves the armature 66 to the right, referringtothe position of the parts in Figure 11. The dog 61 then moves theratchet Y wheel 60 -one'step. The springli` returns the armature 66 tothe full line positionas soon as the energization of the magnet 65terminates.

It will be understood that it is energized foronly `an instant. :Thusthe result of ten triggerv pulls is ten step by step movements of thearm 59, the' parts being so proportioned that the last movement movesthearm. 59 beyond the end of the segmental contact 58 and thus breaksythe circuit and puts the machine out of use. l

At the time that the device is being shot,V and at each closure ofthetrigger switch 54,` the electromagnetic coil 10, referring toFigure'8isenergized and results ,inf a movement of. the solenoid'armature 1iagainst any suitable plate or frame portion-12,'r causing a thud to,sound. A spring, 13 serves to withdraw the-armature 1i when vtheenergization .of the coil terminates. Thus, at every trigger pull, athud sounds, which adds tothe natural effect of the device.`k

, Assuming that the operator so aims his gun 5i as, to direct a-flash oflight through the window 5, the aperture 38 and the lens 36, andenergizes or strikes the photo cell 34,.the .electromagriet or esolenoid 15 is energized. This causes the armature `16 to move to theright, referring to the e position of the parts in which they are shownin Figure 6.v This in turn rotates the trigger member generallyindicated as 11. The upper member or bar 18.then strikes thegdownwardextensions 40 of the target drop, frees the target drop from theAsprings 4i and causes it .tofall forward into the dotted line positionin which itis `shown in 'Figure 6. Since the member "I1 .is pivoted asat 19, its lower armor portion 80 moves in-the op,- posite direction andrstrikes, abellr or chime 8i, herein shown as mounted on any suitable"bracket, v82on. the track structure. .A spring83,as shown vin `Figure 3,normally holdsvthe structure 11 in thefull line Aposition'in which it isVshown vin Figure 6. x u

A hit, in addition to causingthe duck to fall and the chime to sound,operates the scoring device. I illustrate, for example, on any suitablebase 85 a series of individual iixed contacts 86, 86a, etc., which areinsulated from each other. Opposed to them is a moving switch arm 61pivoted as at 88 and operated by the ratchet wheel l 89 which isnormally urged in counterclockwise rotation by the spring 90, thestructure being generally similar to the limit switch structure abovedescribed. 9| indicates an electromagnet which is energized at each hit.When energized, it moves the armature 92 in such fashion as to cause thedog 93 to move the ratchet wheel 69 one step. Retrograde movement of theratchet' wheel is prevented by the detent 94 which is held in operativeposition by the spring Q5 unless and until it is withdrawn by theenergization of the reset magnet 96. Both the shot limit mechanism andscoring device above referred to may be enclosed in housings 51a and65a, respectively, and may be mounted upon the panel The operation ofthe device may be summarized as follows. When the operator inserts acoin and closes the switch 56, the reset magnets 64 and 96 are energizedand both the shot limit switch and the scoring switch are returned tothe initial o1' dotted line positions in which they are shown in Figure11. At the same time, the motor 22 is energized and the targets begin tomove.

When the operator aims and pulls the trigger,

and closes the switch 54, the result is an energization of the light 52and the projection of` a brieiiy timed flash of light from the gun 5|.v'I'he thud sounder 1| also sounds, simulating a shot or the impact of a'bullet against the target.

The operator tries to hit the photo cell by holding his aim on the lens36 which he sees through the aperture 38 of the target drop. If he issuccessiul in hitting the photo cell, he energizes both of theelectromagnets 65 and 9|. The energization of 65, which results eachtime thev trigger switch 54 is closed, merely uses up one shot by movingthe arm 59 one step. The energization of the electromagnet 8|extingulshes the light zero and illuminates the light I to the rear ofthe window aperture 6. In this connection, and asso-- ciated with eachof the contacts V|36, 66a, I may employ an incandescent lamp |0|, lllla,etc. -A'

further result of a hit is the forward-fall of the target drop member3'! which indicates that the bird has been struck and the sounding ofthe chime 8|.

After the operator has taken ten shots, the arm 59 breaks its contactwith the contact 56 and breaks the circuit for the motor 22, thuscausing the targets to cease their motion. By a limit switch structurewhich will later be described, the targets continue to move until theupper target drop is centered midway between the ends of the track, andall further movement then ceases.

The scoring light remains illuminated to indicate the total number ofhits and the device is out of operation until the next ensuing operatorinserts a coin and closes the switch 56.

It will be understood that I may employ a considerable variety ofcircuits in obtaining the above result and I do not wish to be limitedto any specic circuit. I illustrate, however, a practical and operativecircuit which has actually been employed.

In order to provide 'a connection between the cell 34 which is on amoving structure and the necessary amplier and fixed parts, I illustratea Contact track member 91 which may be mounted on any suitableinsulating blocks 96 associated with the cross pieces 28. Opposed to thetracks 91l are contact rollers 99 which may be mounted on springs |00associated with the carriages or bases 30. They may be mounted oninsulating blocks or members |02. The track 91 provides one connectionfor the cell and the other connection may be obtained as by grounding onthe carriage structure.

The indicating lamps |0|, |0|a, etc., may be mounted on a frame |03which is divided into compartments by walls |04. The frame |03 may bemounted upon the panel, for example, by arms |05.

Referring to the wiring diagram of Figures 10 and 11, a source ofoutside 110 volt current is indicated at ||5, ||6, although it will beunderstood that any suitable voltage may be employed and the device maybe operated on direct current. However, for convenience, I illustrate itin connection with 110 volt alternating current. A manually controlledswitch ||1 may be interposed in one of the power lines whereby theentire circuitl may be broken. Shunted across the main power lines' arethe lamps l I6, ||9, which are controlled by the switch ||1. The lamp||9 is illustrated in Figure 1, as mounted at the bottom of the cabinetI, and is visible through a lens |06. The lamp H8 is preferably mountedabove the target structure to illuminate the scenery panels 49, 50 andthe target drops 31. A pair of colored lamps |20, |20 may be mounted ateither side of the lamp l I6; its purpose being to indicate, whenenergized, that the device is in operation.

, Electrically connected with the main power lines H5, I|6 is theprimary winding |2| oi a power transformer T. A second transformer T'has one side of its primary winding |22 connected to the main power line||5. The primary winding of the transformer T serves to energize thesecondary windings |23, |24, |25 and |26. The transformer T is providedwith secondary windings |21, |28 and |29 of which the windings |26 and|29 are electrically connected with the rectifying units |30, |3| whichin turn are connected in series by a line |32. The. secondary coil |21is connected by lines |33, |34 to the plates of a rectifying tube |35associated with any suitable photoelectric amplifier, indicated by A.The electrical circuit of the amplifier A is merely illustrated as anexample, since several well known photoelectric circuits are suitablefor the operation of my invention.

For exempliiication, I have illustrated an amplifying tube |36, the gridelement of which is connected by a line |31 to the rail 91 which in turnis engaged by the rollers 99 on the spring |00 associated with thetarget carriage 30. The spring is electrically connected to the anode ofthe photoelectric cell 34.

In the drawings I have illustrated two target carriages 30, each ofwhich carries a photoelectric cell 34. Since only one target drop isvisible at a time, an electrical rail 91 extending parallel with theupper edge of the rails 23, 24 may be employed as illustrated in Figure5 or, if desired, it may be a continuous rail conforming to the contourof the rails.

Referring back to the diagrams of Figures l0 and 11, the cathode of thephotoelectric cell 34 is diagrammatically connected by a line with aground connection |36. Likewise, the center tap of the secondary winding|21 of the transformer T is grounded as at |39.

'I'he secondary coil |23 of the transformer T supplies current to thefilament of the amplifysecondary coil |24 is connected by the lines |42,|43 to the filament of the rectifyingtube |35. The Vsecondary winding|25 of the transformer T connects to a rectier"|44, the purpose'offwhich will later appear. The end taps'ofsecondary winding |26 areprovided with lines |45; |46 ot" which the line extends to the switcharm 81 of the score indicator. The line |46 is connected to one side ofthe indicating lights |0|, |0|a etc., the'other terminals of'whichareconnected by lines |41 leading yto their respective contacts 86, 86a,etc.

Incorporated inthe electrical circuits belowther,`the rre'ctiiying tube|35 and amplifying tube |36 are energized by the secondary windings- |23and |24. .n

An additional circuit is providedthrough the electromagnet |5| whichpreviously had been established by the limit switch |55, later to bedescribed in detail, which may be traced from the positive terminal ofthe rectifier |44 through line |56, |51,- electromagnet |5|, linel |58,closed switch |59l associated with electromagnet |52, line |60 leadingto the closed switch |6| of electromagnet |5|, thence through lines |62,|63 and' |64 to the negative terminal of the rectifier |44.

Obviously, in the normal operation ofthe device, when'at rest, theelectromagnet |5| is energized and its associated switch members |6| and|65 are in the position indicated in full lines` of Figure 10.

Assumingl the userinserts a coin or token into the coin slide andmanipulates it in the usual manner, he temporarily closes the coincontrolled switch 56, preferably located in a suitable gun cabinet C andcloses the following electrical circuit through the electromagnet |50traceable from the positive terminal of the rectifier |44 through thelines |56, |66, electromagnet|50and line |61 leading to the coincontrolled switch 56,

thence through the lines |68, |69, |10, |63, |64 tov thenegativeterminal of the rectifier |44. Energization of the electromagnet|50 results; in closure of the associated switch members |1|,

|12 and |13 and opening of the switch membersl |14 and |15,completingthereby the following circuits I First, a circuit through theprimary winding |22 of thev transformer T' and simultaneously throughthecoloredvlamps |20, |20, from the main power line ||5 through theprimary winding |22 and` line |16 to the junction point'|11, and theadditional shunt connection |18, lamps |20, |2|-andline |19 leading tosaid junction point |11, thence through lines |80, closed switch |12 andlines' |82, |83 to the other power line |I6. This results inenergization of the vsecondary `windings |21, |28 and-|29 ofthe'transformer T and consequently of the associated circuits previouslydescribed.

An electrical circuit` through the reset magnetsv 64 and96 of the shotlimiting means 51 and score g 'ing tube |36 through thelines |40,V |4|.'I'he indicating device 85, respectively, may now be .traced from thepositive terminal of the rectifier |30, which is connected'in serieswith the rectifier |30, along the lines |84, |85, |86 to the closedswitch |13, thence along the -line |81, line |88r and shunt line |89leadingvto the reset magnets 64' and 96 respectively, thence continuesthrough the lines- |90 land shunt line |9|, the common lines |10, |63,and lines |92, |93 tothe negative 1 terminal of the rectifier |3|.

Inpractice, the negative terminals of both the,

rectifiers |3| .and :|44 as well as the groundy coni nections |38, |39,are grounded 'to the metal frame or panel to eliminate wiring.

' The sh'otlimit switch mechanism'and the score indicating mechanism arethus returned to initial position with the switch members 59 and 8T- iassuming Athe dotted `line position as illustrated inV Figure 11. Thescore indicating lightv |0| is now illuminated as well as the coloredlamps |20, |20 indicating that the device is ready for its cycle ofoperation.

As soon as the operator releases the manually controlled coin slide 55,it automatically vreturns to inoperative position ina well known mannerand opens the switch 56, thusbreaking thecircuit vthrough theelectromagnet |50 above described, and its associated switch membersre-v turn to the position illustrated in Figure 10. That is to say, theswitch members |1|, |12 and :sok

|13are opened and the switch members |14` and |15 are closed.

Energ-ization of the secondary coil |21 of the transformer Tf furtherresults in energizing the amplifier circuits by means of the rectifyingtube |35. The potentiometer 203 of the amplifier A in conjunction withthe cathode of the power output tube |36 is adjusted to venergize thephotoelectric relay |53 when the amplifier circuits are completed andenergized by the transformer T', except for momentary interruptions,when the photoelectric cell 34 is energized or actuated when struck by aflash of light from the gun 5I.

The lphotoelectric amplifierv A is connected by line 204 and lines 205and |43 respectively, with the photoelectric relayk |53, which, whenenergized, closes the switch'members `200, 20| 'and opens the switch 202.

The circuit of the cathode of the poweroutput tube |36 andpotentiometer203 had previously been closed by a switch. 206 associated with theelectromagnet |49 and may partially be traced from the potentiometer 203through lines 201, 208, switch 206, lines 209, 2|0to-the ground |38 andthence to the grounded center tap |39 of thedescribed in detail, thecircuit of the condenser.

2|4 may be traced. from the intersecting point .2|5 inthe line |43leading to the filament of the rectifying tube |35 through the line2.|6,a resistor 2|1, ,line 2|8, a switch 2 |9, associated with theelectromagnet' |49, and a line 220 to the conf denser 2|4, thencethrough lines 2|3, 2|0 and ground |38 to grounded center'tap |39 of thesecondaryy coil |21 of the-transformer T' which in turn is connected bylines |33, |34 to the plates of,y the rectiflllg tube |35,

Closure of the switch 20| of the photoel'ectric relay, |53 closes acircuit through the electromagnet |52, which is traceable from thepositive The electromagnet |52; thus energized, closes K the switchmembers 221, 228 and opens the switch members |59 and 229. The switchmember 228 closes a shunt connection in circuit with theeiectromagnet|52 by means of a line 230, which, in eiect shunts out 'the switchmember 20| associated with the photoelectric relay |53.

Opening of the switchmember |59 interrupts the circuit through theelectromagnet |5| above described and the switch members |6| and |65move to the dotted line position of Figure 10. I'he switch member |65,now closed, completes a'circuit through the ,motor 22 from the mainpower line ||5, through the line 23|, a normally closed switch 232, themotor 22, an adjustable resistor 233, and line 234, to the switch |65,thence through the lines 235, 236, and |83 to the other power line I6.

The motor 22, thence commences to rotate the pulleys |1, which in turnlmoves'the belt |8 and the target carriages 30.

The user may now commence to .shoot at the moving targets. As .soon ashe pulls the trigger 53 of the gun 5| he closes the switch 54momentarily, which results in a flash of light to project from thegunbarrel, simulating in effect a bullet of light."

The gun switch 54 closes a circuit through the electromagnet |49, winchmay be traced as follows: From the positive terminal of the rectifier|30 through the lines |84, |85, 231, the closed switch 14, lines 238,239, to the electromagnet 49, thence through the lines 240, 24|,throughthe gun switch 54 and lines 242, |69, |10, |63, |92, and |93 tothe negative terminal of the rectifier |3|.

'I'he electromagnet |49, thus energized, closes the multiple switchmembers 243, 244, 245, and

24h, and opens the switch members2|9 and 206.

A'Ihe following electrical circuits are thus completed; closure of theswitch member 246 closes' a circuit through-the electromagnets 48, whichmay be traced from the condenser 2| 4, the energizing circuit of whichhasA been previouslyV de scribed, through the lines 2| 3, and 241,leading to the electromagnet |48, thence through the line 248, theswitch member 246, and lines 249 and 220 to the condenser 2|4, In other.words, the

energy stored up in the condenser 2|4 actuates the electromagnet |48when the switch member 246 is closed and the switch member 2|9 isopened.

The electromagnet |48 in turn closes the switch members 250 and 25|, andcloses a circuit through the transformer T-2 in the gun cabinet C whichmay be. traced from. the main power line ||5 through the' lines 23|,252, 253, to the primary coil 254 of the transformer T-2, thence throughthe line 255, switch member 25|, lines 256, 251 to the closed switchmember |15, associated with the electromagnet |50, and'continues throughthe lines 258, |8|, 259, the closed switch member 221, and lines 260,236' and |83, to the other power line ||6. The primary coil 254, of thetransformer T-2 in turn energlzes the secondary coil 26|, and closes acircuit through the gun lamp 52, by means of the line 262 leading fromthe secondary coil to the gun lamp 62 and continues through the lines263, 242, and 264 to the other ,side of the secondary coil 26|.

Note that the electromagnet |46 is energized yonly momentarily by theabove described circuits, .resulting ih illuminating the gun lamp 62 toproduce in eiect a iash of light, which may be called a light bullet. 1Closure Voif the switch vmember 26| associated with the electromagnet|48 closes an electrical 10, thence through the lines 266, the closedswitch.

member 243, lines 261, 251, through the closed switch |15, lines 258,8|, 259, the closed switch member 221, and lines 260, 236, |83, to thevother power line ||6. r In addition the switch member 246, associatedwith thev electromagnet |49 closes a circuit through the electromagnet66 of the shot limiting means, which may be traced from the positiveterminal of the rectifier |30 through the. lines |84, |85, 231, theclosed switch |14, the lines 238, 210, 21|, 212, to the' electromagnet65, thence through the line 213, lthe closed switch member 245, andlines 214, 215, and |93, to the negative terminal of the rectifier |3|,which is connected in Vseries with the rectier |30.

' Energization of the electromagnet 66 results in advancing the switcharm 59 in relation to the 4contact segment 58 one step.

step. If the operator has been successful in obtaining a hit, that is tosay, the flash of light hasf struck the photoelectric cell 34 upon themoving target 30, the additional circuits are completed.

First, energization of the photoelectric cell 34 deenergizes thephotoelectric 'relay |53 momentarily. This in turn opens the associatedswitch members 200, and-20 and closes the switch mem-5 .ber 202.
